What is a Month?

A month is a unit of time we use in our calendars, lasting from 28 to 31 days.

While it's a simple concept we use every day, the story of the month is a fascinating blend of astronomy and ancient history, tied directly to the Moon's cycle.

Why Is a Month About 30 Days Long?

The concept of a month is fundamentally tied to the Moon. A "lunar month" (or synodic month) is the time it takes for the Moon to cycle through all its phases, from one new Moon to the next, which is approximately 29.5 days.

Early civilizations built their calendars around this observable cycle. However, because 12 lunar months (~354 days) don't perfectly align with a full solar year (~365.25 days), calendar months were adjusted to their current, slightly longer, and more varied lengths to keep the seasons in sync with the year.

Where Do the Names of the Months Come From?

Many of our modern month names are inherited from the ancient Roman calendar, which initially had only ten months and started in March. This is why the names for September, October, November, and December come from the Latin words for seven, eight, nine, and ten, respectively.

Later, January (named for Janus, the god of beginnings) and February were added. Months like March were named for the god Mars, while July and August were renamed to honor the influential Roman leaders Julius Caesar and Augustus Caesar.

Why Do Months Have Different Numbers of Days?

The irregular pattern of 28, 30, and 31 days in a month is the result of historical calendar reforms. When the Romans moved from a lunar-based to a solar-based calendar, they needed to spread the days of the year across 12 months.

The system we use today, the Gregorian calendar, is a refinement of the Julian calendar established by Julius Caesar. The specific lengths were a practical solution to make 365 days (and later, 365.25 with a leap day) fit into 12 divisions.

February was left with the fewest days, partly because it was the last month added to the original Roman calendar.

What is a Week (week)?

A week is a familiar unit of time, consisting of seven days.

While we commonly think of it as just seven calendar days, it can also be measured as 168 hours, 10,080 minutes, or 604,800 seconds.

The concept of a seven-day week is one of the oldest and most consistent timekeeping methods in human history.

Why Are There 7 Days in a Week?

Have you ever wondered why a week has exactly seven days?

The tradition dates back thousands of years to the ancient Babylonians. They were skilled astronomers who observed seven celestial bodies moving through the night sky: The Sun, the Moon, Mars, Mercury, Jupiter, Venus, and Saturn.

Believing the number seven held special significance, they structured their calendar in seven-day cycles to honor these celestial bodies.

This system was so practical that it was adopted by neighboring cultures, including the Greeks and Romans, and eventually spread worldwide, becoming the global standard we use today.

Which Day Starts the Week: Sunday or Monday?

While a week is always seven days long, the day it officially begins depends on the time zone in which you are located.

• Sunday marks the beginning of the week in many nations, such as the United States, Canada, and Japan, due to long-standing religious and cultural traditions.
• The international standard ISO 8601, which designates Monday as the start of the week, is widely used in business and government—especially in Europe—to ensure consistency in global communication.
